  • Review Pretreatment Process On Refractory Gold Ores

    Microwave heating has the effect of reducing the tempera ture of chemical reaction So it can avoid generating gases of SO2 and As2O3 by controlling the temperature appropri ately 57 Kyuesi and Haque etc have studied the role of micro wave in the gold extraction process of arsenic bearing refractory gold ore 8 9 Haque K E used microwave.

  • Pdf Cyanidation Of Refractory Gold Ores A Review

    The degree of refractoriness has been classified based on the proportion of gold recovered Table 1 Marsden and House 2009 The gold in refractory sulfide gold ores is surrounded by sulfide.

  • Pretreatment Microwave Pretreatment Of A Refractory Gold

    Microwave Heating Refractory Piaclub Microwave pretreatment of a double refractory gold ore One possible remedy is to roast the ore and thus oxidie the pyrite and remove the organic carbon In this research microwave roasting of a double refractory gold ore was investigated as an alternative method and the results were compared to those.

  • Pretreatment Of Refractory Gold Ore With Microwaves

    Pretreatment of refractory gold ore with microwaves Microwave pretreatment of a double refractory gold ore J Minerals Engineering 2007 2011 1109 11 Study on pretreatment of refractory gold ore by microwave Study on pretreatment of refractory gold ore by microwave roasting method on ResearchGate the professional network for scientists.

  • Microwave Pretreatment Of A Refractory Gold Mc World

    Pretreatment microwave pretreatment of a refractory gold Microwave pretreatment of a double refractory gold 2020 7 20 Abstract Double refractory gold ores such as Barricks Goldstrike ore contain both pyrite and carbonaceous matter and the latter results in the loss of gold from solution during cyanide leaching.

  • Extraction Of Gold From A Lowgrade Double Refractory

    After roasting microwave heating or alkaline pressure oxidation the gold cyanidation ratio reached 82 37 81 26 and 71 09 respectively Roasting was an effective reliable and mature technique to oxidize sulfide minerals and carbonaceous matters.

  • Microwave Pretreatment Of A Double Refractory Gold Ore

    Sep 01 2007018332With regards to the application of microwaves to refractory gold ores Haque 1987a Haque 1987b has studied the microwave pretreatment of refractory sulphidic ores and achieved gold extractions of over 98 However there is no information published on the microwave processing of the double refractory gold ores.

  • Ultrasoundintensified Leaching Of Gold From A Refractory

    The results demonstrated that a maximum gold recovery of 97 was achieved and that gold recoveries of the refractory gold concentrate quickly increased to the maximum with microwave heating time.

  • Removal Of Arsenic And Sulfur From A Refractory Gold

    Jan 01 2010018332It has been demonstrated that microwave heating of primary refractory gold ores not only effectively oxidizes the sulfide matrix and so increases gold recovery during the cyanidation process but also has the potential to significantly reduce the operating cost compared to other pretreatment processes such as autoclave roaster bio oxidation Tranquilla 1997.

  • Microwave Roasting Of Flash Flotation Concentrate

    Jun 01 2020018332Research has confirmed that microwave heating of refractory ores and concentrates effectively oxidises sulphides and carbonaceous matter and liberate gold particles Consequently there are increases in gold extraction during the subsequent cyanidation process.
